Why Do People Get Canker Sores? A Comprehensive Guide

Why Do People Get Canker Sores? A Comprehensive Guide

Introduction: Canker sores, also known as aphthous ulcers, are painful, small, shallow lesions that develop on the soft tissues inside the mouth. They can cause discomfort while speaking, eating, or drinking, and their exact cause is often a subject of concern. In this comprehensive guide, we will delve into the reasons why people get canker sores and how it relates to dentistry. West Hollywood Holistic and Cosmetic Dental Care is dedicated to providing you with valuable insights and strategies to manage and prevent canker sores effectively.

Understanding Canker Sores

Canker sores are not contagious and typically resolve on their own within one to two weeks. However, they can recur frequently in some individuals. They often manifest as round or oval-shaped white or yellowish sores with a red border. Canker sores can appear on the inner cheeks, gums, tongue, lips, or even the roof of the mouth. While their exact cause remains uncertain, several factors contribute to their development.

Top 10 Reasons People Get Canker Sores

  1. Trauma or Injury: Accidentally biting the inside of your cheek, brushing too vigorously, or wearing ill-fitting dental appliances can cause canker sores to form.
  2. Hormonal Changes: Fluctuations in hormone levels, such as those experienced during menstruation, pregnancy, or menopause, can increase the likelihood of developing canker sores.
  3. Stress and Emotional Factors: High levels of stress, anxiety, or emotional turmoil can weaken the immune system, making you more susceptible to canker sores.
  4. Nutritional Deficiencies: Inadequate intake of essential vitamins and minerals, particularly vitamin B12, iron, zinc, or folic acid, can contribute to the formation of canker sores.
  5. Food Sensitivities and Allergies: Certain foods, such as citrus fruits, spicy foods, chocolate, coffee, and nuts, can trigger canker sores in sensitive individuals.
  6. Autoimmune Disorders: Conditions like Crohn’s disease, celiac disease, and Behçet’s disease, which affect the immune system, can increase the risk of canker sores.
  7. Weakened Immune System: Chronic illnesses, HIV/AIDS, and medications that suppress the immune system can reduce your body’s ability to fight off infections, leading to canker sores.
  8. Oral Hygiene: Poor oral hygiene, including infrequent brushing and flossing, can create an environment conducive to the development of canker sores.
  9. Chemical Irritants: Certain oral care products containing sodium lauryl sulfate (SLS), a foaming agent, can trigger canker sores in individuals who are sensitive to it.
  10. Genetic Predisposition: Some individuals have a higher genetic susceptibility to canker sores, making them more prone to developing these oral lesions.


While the precise cause of canker sores remains elusive, understanding the various factors that contribute to their occurrence can help manage and prevent them effectively. West Hollywood Holistic and Cosmetic Dental Care encourages a comprehensive approach to oral health, addressing underlying issues, and providing personalized treatment plans to alleviate discomfort and prevent future occurrences of canker sores. By maintaining good oral hygiene practices, managing stress, adopting a balanced diet, and seeking professional dental care, you can minimize the frequency and severity of canker sores, promoting a healthier, more comfortable smile. Remember, if you experience persistent or unusually severe canker sores, it is always advisable to consult with a dental professional for a thorough evaluation and appropriate treatment options.
